Fixed Focus Fiber Collimators

Besides adjustable collimators, we also manufacture large fixed focus collimators for communications, lidar, interferometry and metrology. FCX20 generates beam diameters of 11.5 mm at 1550 nm with low wavefront error. Other wavelengths at 1064 nm and 640 nm are suitable for lidar and interferometry. Fiber choices include single-mode and polarization-maintaining fibers. Other wavelengths are possible as well as customization for your application.
